In PCMARK05, Vista kills XP, in other benchmarks it's slightly better, the same, or slightly worse, but none of the differences in the other benchmarks would be perceptible to humans. The author says basically early gaming problems with Vista were due to bad graphics drivers that have been fixed. Vista SP1 leads by enough in PCMARK05 to win overall, unless I'm missing something. Just food for thought/debate.
